A gastrula is an embryo in the cell organization of development, when the three germ layers form. This is called gastrulation, and the three layers are the endoderm, mesoderm, and ectoderm.
A neurula is an embryo at the stage of development when the nervous system begins developing, called neurulation. Neurulation happens after gastrulation.
The correct order of developmental sequence is: Fertilization -> Zygote -> Cleavage -> Blastula -> Gastrula -> Embryo -> Meiosis -> Adult.
The blastula is an embryonic structure that is formed from one cell layer. This later forms the three cell layered gastrula. All of the layers of the organism are formed from these three layers. See the link below:
The layers of the gastrula are the ectoderm, endoderm, and mesoderm. These layers give rise to different tissues and organs in the developing embryo during the process of gastrulation.
Gastrula has cell layers that will later develop into different body structures. The three primary germ layers - ectoderm, mesoderm, and endoderm - are formed during gastrulation and give rise to various tissues and organs in the developing embryo.
The opening outside of the gastrula is called the blastopore. It is the initial opening that forms during gastrulation, where cells migrate to form the three germ layers.
1) How is a Gastrula different from the Blastula?
1) How is a Gastrula different from the Blastula?
Surely it is the gastrula. The fertilized egg contains only one copy of the genome, while the gastrula contains thousands copies of the genome.
The endoderm of the gastrula turns into internal organs such as the liver and pancreas, and into the lining of some systems.
The blastula is the developmental stage that forms before the gastrula. During embryonic development, the blastula undergoes a process called gastrulation, which results in the formation of the gastrula.
